Knowles Johanson Manufacturing's Giga-Trims are tiny trimmer capacitors that provide a straightforward technique for fine RF and microwave circuits by eliminating time-consuming methods of abrasive trimming, cut and try adjustment techniques, and interchange of fixed capacitors.

The design evolved from the need for a virtually indestructible miniature trimmer with superior electrical characteristics. Giga-Trim capacitors withstand the rigors of soldering heat, excessive tuning, and rough handling. As a result of the excellent dielectric and insulation properties of the sapphire housing, high breakdown voltage is achieved. Incorporating the patented self-locking constant torque drive mechanism which eliminates the need for external bushing slots, the new Giga-Trim offers many improvements: a fixed length, increased Q, essentially zero tuning noise, and reduced susceptibility to solder flux intrusion during installation.
